SECTION 401

Paving operations shall not resume until the Engineer determines that material meeting the Contract requirements can be

produced. Corrective action will be considered acceptable by the Engineer if the pay factor for the failing property increases. If

it is determined that the resumption of production involves a significant change to the production process, the current lot will be

terminated and a new lot will begin.
3.17.3.6.3 Remeasure and Retest. All requests to the Engineer to remeasure and retest a sublot shall be in writing.

Method of Measurement

4.1 Asphalt pavement mixture will be measured by the ton to the nearest 0.1 ton, and in accordance with 109.01. Batch weights
will be permitted as a method of measurement only when the provisions of 3.8.3 are met, in which case, payment will be based
on the cumulative weight of all the batches. The quantity will be the weight used in the accepted pavement, and no deduction
will be made for the weight of asphalt binder or additives in the mixture.

4.1.1 Hot bituminous pavement, machine or hand method (night) will be measured in the same manner as 4.1. No separate
measurement will be made for lighting necessary or overtime required due to night operations at the plant or at the site.

4.1.2 Due to possible variations in the specific gravity of the aggregates, and to possible field changes in areas to be paved,
the quantity used may vary from the proposal quantities, and no adjustment in Contract unit price will be made because of such
variations.

4.2 Asphalt pavement, removed because of faulty workmanship or contamination by foreign materials, will not be included in
the pay quantity.
4.3 Blank,

4.4 Joint adhesive will be measured by the linear foot for each lift of pavement to be placed, to the nearest foot of adhesive
applied. Ifthe Contractor chooses to pave in echelon in lieu of using joint adhesive, payment for the length of joint eliminated
by the echelon paving will be made,

4.5 Echelon paving, when specified or approved, will be measured by the linear foot along the shared edge of the mats being
simultaneously placed.

Basis of Payment

5.1 All work performed and measured as prescribed above will be paid for at the Contract unit price as provided in the respective
sections for each type specified.

5.2 Tack coat material ordered under 3.10.10 will be paid as provided for in Section 410.
5.3. Blank.

5.4 Plant or project site lighting for hot bituminous pavement, machine or hand method (night), or overtime required due to
night operations will be subsidiary to the paving items.

5.5 Asphalt cement additives will be subsidiary to the paving items.

5.6 Implementation of the Quality Control Plan and costs associated with obtaining core samples for acceptance testing shall
be subsidiary. When items are to be accepted under Quality Assurance provisions, pay adjustment will be made in accordance
with 106.03.2.4 as specified below,

5.6.1 Gradation composite pay factor (CPF). The total price for each lot will be adjusted by a composite pay factor
(CPF) based on the gradation of the material after extraction using the pay factors for each sieve size and the sieve size weight

3.1 Limitations. Bituminous material shall not be applied on a wet surface, or when weather conditions would prevent the proper
application and curing of the coat. The quantities, rate of application, temperatures, and areas to be treated shall be approved before
application of bituminous material.

3.2 Equipment.
Equipment required for this work shall be as follows:

(a) A distributor shall be so designed, equipped, maintained, and operated such that bituminous material at even heat may be
applied uniformly on variable widths of surface up to 12 ft, at readily determined and controlled rates from 0.02 to 2.0
gal/yd?, with uniform pressure, and with an allowable variation from any specified rate not to exceed 0.02 gal. Distributor
equipment shall include a tachometer, pressure gauges, accurate volume measuring devices or a calibrated tank, and a
thermometer for measuring temperatures of tank contents. Distributors shall be equipped with a power unit for the pump
and with full circulation spray bars adjustable laterally and vertically. The spray bar shall contain spray nozzles providing
a fan-shaped spray pattern adjusted so the vertical axis is perpendicular to the pavement surface. The spray pattern and
spray bar height shall be adjusted to provide a uniform application of the tack coat without double coverage. The
distributor shall be equipped with a mechanical device to adjust the spray height as material is discharged to keep a
uniform height above the pavement for full coverage without overlapping. The distributor shall also be equipped with a
hand-held spray attachment for applying the material to areas inaccessible to spray bars and to fill in irregular areas to
provide full coverage. Approved sampling valves shall be installed in distributors and transport tank trucks to permit
taking representative samples of the contents. The recommended location of the sampling valve is in the rear bulkhead of
the tank roughly one-third of the height above the bottom. The inlet pipe shall project into the contained liquid as shown
in AASHTO T 40. At least 1 qt of material shall be drained off through the sampling valve and discarded before the
desired sample is taken. New sample containers will be furnished by the Engineer. To prevent the loss of solvents,
containers shall be sealed with a tight fitting cover immediately after being filled.

(b) A rotary power broom for sweeping treated surface.

(c) A steel-wheeled roller.

(d) A self-propelled pneumatic-tired roller.

{e) A sand spreader capable of spreading blotter material in sufficient quantity to prevent traffic pickup of the applied
bituminous material.

(f) A steel-brush drag of an approved type.

3.3 Preparation of Surface to be Treated.
